Full of nonsense

1 The samples are generally too low to be sensible

2 As far as I am aware Angenieux have never made DSLR lenses and dont make Distagons, Carl Zeiss do.

3 You cannot compare MTF values for 35mm, APSC, MF and 16mm cine lenses.

I fail to see how the quality of a lens can be judged soley by its MTF rating. There are so many variables in what makes a good lens.
Even if focal length & aperture are fixed, for some applications smooth Bokeh might be vital where for others edge to edge sharpness would be critical.

How can you judge who makes teh best lenses when they have used data from the worst lenses as well, thats ridiculous, it should be who has the highest ranked lenses based on MTF across its whole range..

In overall terms, I would say that the best lenses were and are made by the major marques, but many manufacturers have some classics.

The Zeiss 80mm f2.8 for Hasselblad has to be a major contender, the f4.5 Apo-Lanthar from Voigtlander another, for 6x9cm.

Several lenses from Canon, Nikon, Pentax and Contax.

Not so many from Konica and Fujifilm.

Classic macro lenses abound.

Lenses have a character and MTF tests are not be be and end all.

I agree.

It's impossible to be objective about what's a best lens. The requirements and subjectivity of each photographer is going to be very diverse and those two factors are what determines what is the best lens for each individual.

Not impossible. There are cetain things that are generally agreed upon and although we may not actually require the particular characteristics of a given lens, we could recognise that for its purpose it is a superior lens.

For example, an 85mm designed to be soft wide open we could recognise as being good for portraits. Portrait photographers generally might swear by it. However, if we needed an 85mm that was crisp wide open, then it would be little use to us. We could still objectively recognise its qualities.

John, I used to work with a Konica Autoreflex T3, and I think the lenses I had with the Konica were among the best I've had. Unfortunately, due to the short register distance used by Konica, they can't be used with other makes.


I would have put them against any Nikon or Canon lens in the same category, and I'm sure they would not have been lagging behind.

Let's not forget Minolta. Many of their Rokkor-X offerings were up with the best of them. I still use the 50mm 1.4 occasionally on my old Minolta XK and it's crackingly sharp (not, of course, in the same league as Pentax ). I used it professionally for several years and wouldn't have done this if it wasn't up to the job.

Once you got away from the mass market lenses Olympus made
some pretty good stuff including f/2.0's at every
focal length up to (at least) 250mm

The 180mm reached 69 and 62 lpmm at f/4 way better than
everything else.... see this page at the bottom:
